Connector capable of suppressing separation of lid from housing

Abstract

A connector includes small-diameter shielded terminals 51 that are connected to small-diameter shielded electric wires 61 , and a housing 10 that includes wide terminal housing parts 73 and a narrow terminal housing part 74 . The wide terminal housing parts 73 include wide holding parts 35 and a lid part 41 . The narrow terminal housing part 74 includes a narrow holding part 36 and the lid part 41 . The lid part 41 includes a plate-like covering part 42 that covers openings in the wide holding parts 35 and the narrow holding part 36 , and elastic pressure-receiving parts 43 that protrude from the plate-like covering part 42 into the wide terminal housing parts 73 and the narrow terminal housing part 74 and are elastically deformable under pressing forces of the small-diameter shielded electric wires 61 or the coated electric wire 67.

What is claimed is: 
     
       1. A connector comprising:
 a terminal metal fitting that is connected to a front end portion of an electric wire; and 
 a housing including a terminal housing, 
 wherein, in a state where the terminal metal fitting and the front end portion of the electric wire are housed in the terminal housing, the electric wire is drawn out from a rear surface of the housing to the outside of the housing, 
 the terminal housing includes:
 a holding portion with a U-shaped cross section; and 
 a lid that is formed of a member separate from the holding portion, and 
 
 the lid includes:
 a plate-like cover that covers an opening in the holding portion; and 
 an elastic pressure-receiving portion that protrudes from the plate-like cover into the terminal housing, and 
 
 in a state where the lid is attached to the holding portion, the elastic pressure-receiving portion is elastically deformable under a pressing force of the electric wire such that the pressing force toward the lid is distributed between the plate-like cover and the elastic pressure-receiving portion. 
 
     
     
       2. The connector according to  claim 1 ,
 wherein the holding portion includes:
 a base portion that opposes the plate-like cover; and 
 a pair of side wall portions that extend from two side edges of the base portion toward the plate-like cover, 
 
 a plurality of the elastic pressure-receiving portions are respectively arranged along the side wall portions, and 
 when the elastic pressure-receiving portions are elastically deformed under the pressing force of the electric wire, the elastic pressure-receiving portions are pressed against the side wall portions. 
 
     
     
       3. The connector according to  claim 2 ,
 wherein an area of each of the elastic pressure-receiving portions that comes in contact with the electric wire is formed by an inclined surface that is inclined with respect to a direction that is orthogonal to the plate-like cover. 
 
     
     
       4. The connector according to  claim 2 ,
 wherein, in a state where the elastic pressure-receiving portions are pressed against the side wall portions, the electric wire is kept in a state of non-contact with the plate-like cover. 
 
     
     
       5. The connector according to  claim 1 ,
 wherein, in a rear view of the housing as seen from a rear side, the elastic pressure-receiving portion has a wedge shape that is tapered toward a leading end thereof in a direction of protrusion from the plate-like cover. 
 
     
     
       6. The connector according to  claim 1 ,
 wherein, in a rear view of the housing as seen from a rear side, a pair of the elastic pressure-receiving portions are provided so as to be symmetrical with respect to a virtual axis of symmetry that is orthogonal to the plate-like cover. 
 
     
     
       7. A connector comprising:
 a terminal metal fitting that is connected to a front end portion of an electric wire; and 
 a housing including a terminal housing, 
 wherein, in a state where the terminal metal fitting and the front end portion of the electric wire are housed in the terminal housing, the electric wire is drawn out from a rear surface of the housing to the outside of the housing, 
 the terminal housing includes:
 a holding portion with a U-shaped cross section; and 
 a lid that is formed of a member separate from the holding portion, and the lid includes: 
 a plate-like cover that covers an opening in the holding portion; and 
 an elastic pressure-receiving portion that protrudes from the plate-like cover into the terminal housing and is elastically deformable under a pressing force of the electric wire, 
 
 the holding portion includes:
 a base portion that opposes the plate-like cover; and 
 a pair of side wall portions that extend from two side edges of the base portion toward the plate-like cover, 
 
 a plurality of the elastic pressure-receiving portions are respectively arranged along the side wall portions, and 
 when the elastic pressure-receiving portions are elastically deformed under the pressing force of the electric wire, the elastic pressure-receiving portions are pressed against the side wall portions. 
 
     
     
       8. The connector according to  claim 7 ,
 wherein an area of each of the elastic pressure-receiving portions that comes in contact with the electric wire is formed by an inclined surface that is inclined with respect to a direction that is orthogonal to the plate-like cover. 
 
     
     
       9. The connector according to  claim 7 ,
 wherein, in a state where the elastic pressure-receiving portions are pressed against the side wall portions, the electric wire is kept in a state of non-contact with the plate-like cover. 
 
     
     
       10. The connector according to  claim 7 ,
 wherein, in a rear view of the housing as seen from a rear side, the elastic pressure-receiving portion has a wedge shape that is tapered toward a leading end thereof in a direction of protrusion from the plate-like cover. 
 
     
     
       11. The connector according to  claim 7 ,
 wherein, in a rear view of the housing as seen from a rear side, a pair of the elastic pressure-receiving portions are provided so as to be symmetrical with respect to a virtual axis of symmetry that is orthogonal to the plate-like cover.
